Kit is great but took over a week to arrive when I'd paid for 24h shipping, and has absolutely no instructions of any kind. I can get this information elsewhere but it would have been helpful and just made sense to have included literally any kind of helpful info in the kit. I have been asked to change my review after being told that the parcel had to be redelivered three times but considering I am disabled and not currently able to leave my house this isn't true. As I say the kit is good but don't bother paying extra for fast shipping. And it would have been easy and more helpful for some people to include printed out info with the kit, so I stand by my original review.
